Air conditioning blamed for 20 percent of illnesses in summer

Too cold air conditioning is responsible for 20 percent of all illnesses registered in the Czech Republic during the summer months, Jakub Nožička of the Česká pojišťovna insurance firm told the news website novinky.cz on Saturday. Block vertebrae, headaches and joint pain are among the most common problems caused by big differences in temperatures between in- and outdoors, doctors say; they warn that the difference between temperatures in air-conditioned spaces and outside should not be higher than five degrees Celsius.
